The Sum of Two Unbounded Linear Operators: Closedness, Self-adjointness and Normality
MH Mortad - arXiv preprint arXiv:1203.2545, 2012 - arxiv.org
In the present paper we give results on the closedness and the self-adjointness of the sum of
two unbounded operators. We present a new approach to these fundamental questions in …
